Electoral results and the geographical allocation of public investment in Greece have been intimately related. This column describes how incumbent Greek governments between 1975 and 2009 tended to reward those constituencies returning them to office. Increases in both the absolute and relative electoral returns for the party in government in a given Greek region were traditionally repaid with a greater level of per capita investment in that region. Single-member constituencies were the greatest beneficiaries of this type of pork-barrel politics.

Piketty's justification for his proposed wealth tax relies on the notion that the rate of return on capital exceeds economic growth. This column challenges this basis, arguing that it fails to account for risk. The authors also examine the relative merits of a consumption tax, which may be more valid.

Following the Warsh Review, the recording, number, and timing of the Bank of England’s Monetary Policy Committee meetings will change. This column argues that the recording may make the decision meeting more formal and could inhibit debate, although the eight-year gap before publishing transcripts ameliorates this concern. Having fewer MPC meetings is a good thing, and reduces ‘noise’ around monetary policy. The revised meeting schedule will not add to transparency and raises the risk of leaks and ‘news shocks’.

The European Commission has clarified the flexibility in existing Eurozone fiscal rules. This column argues that the emphasis on structural rather than headline deficits is desirable but requires identification of potential growth rates. The way the Commission currently estimates potential output yields potential growth estimates that are very low. Thus, a year of modest expected growth like 2015 may be treated as a year of economic boom that requires faster than normal fiscal adjustments.
